Ioannis Vvolphii Tigurini De officio praeconis evangelici oratio, qua D. Pauli 2. Timoth. 2. locus explicatur, Stude teipsum probatum exhibere Deo, operarium non erubescendum, recte secantem sermonem veritatis

...shoulders, we who are to preach the Gospel, those cannot be unaware who consider that we must instruct every kind of person on what is becoming or unbecoming, what is harmful or expedient, in what way there is an escape from human evils and miseries, and by what way one should strive toward the highest good in the most direct and safe manner. For they understand that the matter itself requires that this be done rightly and duly, so that we ourselves may attract men to duty not so much by oratory and words as by our own example, and finally, so that we ourselves may be inclined by our own nature toward that which we wish to persuade others. Therefore, the task of him who wishes to perform what we have just said is heavy and arduous; but it is much heavier for him who, as if he had already achieved these good things himself, professes that he will demonstrate and hand them over to others. For this reason, that frequent assembly of yours has always seemed most pleasant to me, and this old custom of exhorting most august; but you wished for this place to be open most of all to the best men. Therefore, I believe you, venerable men, wonder why it is that when so many excellent theologians and most learned men have gathered, I have risen above all, I who cannot be compared in age, nor in talent, nor in authority with those who are present.
